|MPRovEMENT IN NEEDL-Es. j

I -Spaliieation forming part oi' Letters Raienl: No. 37,996, lated March 24, 1863.

fo all whom -it may concern: Y .Be it'known that l, AUGUSTINE I. AMBLER, of (alle city of Milwaukee, in the county of Milwaukeeend State of Wisconsin, have Invented a new and useful Improvement; in Needles; and Vl do` herebyfdeclare that the following is n full, clear, and exact description ofthe same, reference being had to the accompanying drawings, thrilling parl; of this specification, in whieh l A Figures 1' and 2 are side vviews, on an en larged scaligoi' sewing-machine needles 'with my improvement. Fig 3 is ai side view of a needle {arnaud-sewing, with the im poo-vement.

Similar letters o i'greference indicate' orrespending parts, in the several figures. l

In the seieral views of the drawings, a is the eye 'ofthe needle, made ofthe usual elongated form; and b is the slot mauein one'side of the eye. The outer edges of the slot are beveled on the outside .to prevent` their catch-l ing in the cloth or other material being sewed.,

In constructing the needle with the slotted eye, inoreespecially the lnaehinefneedle, it is preferable to make the eye alittle nearer to that side in which the slot is formed or else to pensa-ted `for, and il; is rendered stiffer than ifthe eye'were in the center andthe point in the center line or axis.

l The slot b does notJ impair the elciency of the needle, either l'r hand ormachine sewing, experiment;l showing it to Work :is Well as when tlie eye is unbroken ou boihside's.`

Having thus described my invention, I claim and desire to, secure by Letters Batenb- As an improved article of manufacture, a needle made 'with a lateral hevelednpeniny; into the eye and anincreased thickness of metal on the side ofthe needle opposite the opening, all as herein shown amldesclfihed.
